Abstract (en)

[origin: US2013083389A1] A photonic integrated circuit and related method are presented. A photonic integrated circuit comprises a source of radiation, one or more optical amplifiers, a transceiver, and optical waveguides. The optical waveguides couple light between the source of radiation, the one or more optical amplifiers, and the transceiver. The one or more optical amplifiers are configured to increase an optical power of the light up to at least 10 mW. The photonic integrated circuit may be used to perform laser Doppler velocimeter type measurements.
